Where is the water pump located on my Dockstream RFID Smart Fountain?

The Dockstream RFID Smart Fountain is different from the previous Dockstream water fountain, as the main unit does not come with a separate wireless water pump.
The water tank has a stainless steel shaft embedded in it, and the rotor is already installed on the shaft.
You just need to remove the water pump cover with the black foam to see it.
 
As a friendly reminder, the pump rotor, pump cover, and black foam filter of the Dockstream RFID Smart Fountain are detachable and located inside the water tank.
For your reference, I’ve attached unboxing photos.
